WebOct 30, 2024 · Fracture toughness is a measure of the amount of energy required to fracture a material that contains a crack. The tougher the material, the more energy required to cause a crack to grow to fracture. For a particular alloy, lower fracture toughness corresponds to less ductility. For example, glass has very low toughness and is very brittle. WebA method for measuring fracture toughness of soft sediments is proposed in this paper. The gas injection tests on soft soil at constant flow rate were conducted, and the fracture toughness of soft soil could be calculated combined with the theory of linear elastic fracture mechanics based on the gas pressure and the orifice diameter.
